Is it COVID-19? Flu? At-home rapid tests could help you and your doctor decide on a treatment plan
At-home rapid tests for COVID-19 and influenza are becoming available, allowing simultaneous diagnosis, which aids timely and effective treatment and improves patient outcomes.

A scratchy, sore throat, a relentless fever, a pounding head and a nasty cough – these symptoms all scream upper respiratory illness. But which one?
Many of the viruses that cause upper respiratory infections such as influenza A or B and the virus that causes COVID-19 all employ similar tactics. They target the same areas in your body – primarily the upper and lower airways – and this shared battleground triggers a similar response from your immune system. Overlapping symptoms – fever, cough, fatigue, aches and pains – make it difficult to determine what may be the underlying cause.
Now, at-home rapid tests can simultaneously determine whether someone has COVID-19 or the flu. Thanks in part to the National Institutes of Health’s Rapid Acceleration of Diagnostics, or RADx, program, the Food and Drug Administration has provided emergency use authorization for seven at-home rapid tests that can distinguish between COVID-19, influenza A and influenza B.
Our team in Atlanta – composed of biomedical engineers, clinicians and researchers at Emory University, Children’s Healthcare of Atlanta and Georgia Institute of Technology – is part of the RADx Test Verification Core. We closely collaborate with other institutions and agencies to determine whether and how well COVID-19 and influenza diagnostics work, effectively testing the tests. Our center has worked with almost every COVID and flu diagnostic on the market, and our data helped inform the instructions you might see in many of the home test kits on the market.
While no test is perfect, to now be able to test for certain viruses at home when symptoms begin can help patients and their doctors come up with appropriate care plans sooner.
A new era of at-home tests
Traditionally, identifying the virus causing upper respiratory illness symptoms required going to a clinic or hospital for a trained medical professional to collect a nasopharyngeal sample. This involves inserting a long, fiber-tipped swab that looks like a skinny Q-tip into one of your nostrils and all the way to the back of your nose and throat to collect virus-containing secretions. The sample is then typically sent to a lab for analysis, which could take hours to days for results.
Thanks to the COVID-19 pandemic, the possibility of using over-the-counter tests to diagnose respiratory illnesses at home became a reality. These tests used a much gentler and less invasive nasal swab and could also be done by anyone, anytime and in their own home. However, these tests were designed to diagnose only COVID-19 and could not distinguish between other types of illnesses.
Since then, researchers have developed over-the-counter multiplex tests that can screen for more than one respiratory infection at once. In 2023, Pfizer’s Lucira test became the first at-home diagnostic test for both COVID-19 and influenza to gain emergency use authorization.
What are multiplex rapid tests?
There are two primary forms of at-home COVID-19 and COVID-19/flu combination tests: molecular tests such as PCR that detect genetic material from the virus, and antigen tests – commonly referred to as rapid tests – that detect proteins called antigens from the virus.
The majority of over-the-counter COVID-19 and COVID-19/flu tests on the market are antigen tests. They detect the presence of antigens in your nasal secretions that act as a biological signature for a specific virus. If viral antigens are present, that means you’re likely infected. https://www.youtube.com/embed/s45GMoZaHFE?wmode=transparent&start=0 Respiratory illnesses such as flu, COVID-19 and RSV can be hard to tell apart.
To detect these antigens, rapid tests have paper-like strips coated with specially engineered antibodies that function like a molecular Velcro, sticking only to a specific antigen. Scientists design and manufacture specialized strips to recognize specific viral antigens, like those belonging to influenza A, influenza B or the virus that causes COVID-19.
The antibodies for these viral targets are placed on the strip, and when someone’s nasal sample has viral proteins that are applied to the test strip, a line will appear for that virus in particular.
Advancing rapid antigen tests
Like all technologies, rapid antigen tests have limitations.
Compared with lab-based PCR tests that can detect the presence of small amounts of pathogen by amplifying them, antigen tests are typically less sensitive than PCR and could miss an infection in some cases.
All at-home COVID-19 and COVID-19/flu antigen tests are authorized for repeat use. This means if someone is experiencing symptoms – or has been exposed to someone with COVID-19 but is not experiencing symptoms – and has a negative result for their first test, they should retest 48 hours later.
Another limitation to rapid antigen tests is that currently they are designed to test only for COVID-19, influenza A and influenza B. Currently available over-the-counter tests aren’t able to detect illnesses from pathogens that look like these viruses and cause similar symptoms, such as adenovirus or strep.
Because multiplex texts can detect several different viruses, they can also produce findings that are more complex to interpret than tests for single viruses. This may increase the risk of a patient incorrectly interpreting their results, misreading one infection for another.
Researchers are actively developing even more sophisticated tests that are more sensitive and can simultaneously screen for a wider range of viruses or even bacterial infections. Scientists are also examining the potential of using saliva samples in tests for bacterial or viral infections.
Additionally, scientists are exploring integrating multiplex tests with smartphones for rapid at-home diagnosis and reporting to health care providers. This may increase the accessibility of these tests for people with vision impairment, low dexterity or other challenges with conducting and interpreting at-home tests.
Faster and more accurate diagnoses lead to more targeted and effective treatment plans, potentially reducing unnecessary antibiotic use and improving patient outcomes. The ability to rapidly identify and track outbreaks can also empower public health officials to better mitigate the spread of infectious diseases.

Cruise travel is having more than a moment. It’s having a decade.
(Tiffany Miller) The cruise industry is not waiting for travelers to come around. By most measures, they already have. A projected 21.7 million Americans are expected to cruise in 2026, a record high and a 4.5 percent increase over last year, according to AAA.
“Cruising has come a long way since The Love Boat,” said writer and travel expert Sarah Greaves-Gabbadon, aka JetSetSarah. “Pull up to the port, unpack once and have the world come to you.”
This April, more than 11,500 attendees and 650 exhibitors gathered at Seatrade Cruise Global to map out what comes next.
Dining as the main event
Food has always been part of the cruise experience. The question the industry is now asking is what happens when it becomes the point.
Cruise lines are placing greater emphasis on the dining experience, with destination-inspired menus, port-specific drinks and more immersive, multi-course experiences.
Royal Caribbean introduced the Empire Supper Club this year, pairing multi-course menus with craft cocktails and live music into a single evening.
Expedition cruising finds a new audience
Expedition cruising is one of the fastest-growing types of cruising, and major cruise lines are moving into it.
These itineraries go where other ships do not. Travelers kayak among glaciers, contribute to citizen science programmes and spend time in the field with naturalists and researchers, with programming built around science and conservation rather than port stops.
National Geographic-Lindblad Expeditions has operated in this space for decades, with programs including the Visiting Scientist Program, the Lindblad Expeditions-National Geographic Fund and the Grosvenor Teacher Fellowship.
Wellness expands across the ship
Wellness is no longer a spa deck. It is becoming a reason to book.
A few years ago, a thermal suite was a selling point. Now it is closer to a baseline expectation. Meditation spaces, sleep-focused staterooms and recovery lounges are following the same trajectory. A dedicated wellness pavilion debuted at this year’s show, a signal that the category has grown large enough to need its own floor space.
Cunard’s Wellness at Sea program runs across multiple days. Its three tracks (Relax, Energise and Recover) each combine fitness, spa and mindfulness elements. Shore excursions and destination-specific spa offerings carry the experience beyond the ship.
Ships as cultural hubs
Entertainment on cruise ships used to mean a stage show. Cruise lines are now producing content that doesn’t exist anywhere else.
Holland America Line partnered with The Verdon Fosse Legacy to debut “Fosse and Verdon, The Duet That Changed Broadway,” a live musical and multimedia tribute to the work of Bob Fosse and Gwen Verdon. The production marks the first international staging of their work at sea.
Onboard retail is moving in the same direction. More cruise lines are curating locally sourced goods and destination-specific products at port, the kind passengers could only find by actually being there.
The bigger picture
The passenger numbers tell one part of the story. What cruise lines are building inside that growth tells another.
“Today’s ships offer amenities that are at least as good as, and often more comprehensive than, those in resorts and hotels,” Greaves-Gabbadon said. “A cruise can be equally enjoyable for solos, families, honeymooners, groups and adventurers, and that versatility is a large part of their appeal.”
What the show floor made clear is that the industry is not waiting to be discovered. It is building toward the traveler it wants next.
